# Read and Write JPEG

Reads and writes image in JPEG format.

## Instruction

Write a C# program that loads a JPEG image, vertically flips it, and saves it using high-quality JPEG encoding settings including 90% quality, no chroma subsampling, and progressive mode enabled.

## Usings

```csharp
using Aurigma.GraphicsMill.Codecs;
using Aurigma.GraphicsMill.Transforms;
```

## Code Snippet

```csharp
using (var bitmap = new Bitmap("Chicago.jpg"))
{
    bitmap.Transforms.Flip(FlipType.Vertical);

    var jpegSettings = new JpegSettings()
    {
        Quality = 90,
        UseSubsampling = false,
        IsProgressive = true,
    };

    bitmap.Save("ReadWriteJpeg.jpg", jpegSettings);
}
```

## Explanation

Here is a C# program that reads a JPEG image, flips it vertically, and saves it as a new JPEG file with specific compression settings:

This code loads an input JPEG file, applies a vertical flip, and saves it as an output JPEG using 90% quality, progressive encoding, and no chroma subsampling.
